The fact that Srinivasa Ramanujan Iyengar has a feature film on his life called The Man Who Knew Infinity: A Life of the Genius Ramanujan speaks volumes about the greatness of this Indian-born mathematician. The downside to his great intellect? He was so far ahead of his time and his work was so unorthodox, that even the most celebrated scholars of his times couldn’t really understand him! It is only now, more than 80 years after he passed away that we are beginning to comprehend his work and apply it to computing and complicated physics.
Thanks to the English mathematician G H Hardy, Ramanujan came to England. But he was known for certain quirks. For instance, he refused point blank to wear shoes or socks. People started referring to him as a nutcase as he was in the habit of lying face down in a cot while working on mathematical problems, and that too on a slate with chalk rather than using pen and paper. The most infuriating habit of all – especially to his fellow mathematicians – was that Ramanujan would rub out all his complicated workings with his elbow once he solved a mathematical problem and just leave behind the solutions on his slate! As a result of which mathematicians, even today, are still in the process of figuring out how exactly this mastermind worked them all out so correctly.
The most popular story about Ramanujan comes from a visit G H Hardy made to him when he was on his deathbed. Hardy didn’t know what to say to cheer him up, so he commented on the boring number of his taxi – 1729. Our genius, even in that ill state, was instantly inspired and sat up: “1729 is a fascinating number! It is the smallest number that can be expressed as the sum of two cubes in two different ways!”
In his short yet extremely fruitful life, this mathematical prodigy rediscovered previously known theorems, produced new theorems of his own accord, independently compiled nearly 4000 results of identities and equations and made remarkable contributions to the fields of mathematical analysis, number theory, infinite series and continued fractions.
G H Hardy summed it up perfectly when he said: “Here was a man who could work out modular equations and theorems to orders unheard of, and whose mastery of continued fraction was beyond that of any mathematician in the world.” Undoubtedly, he was one of a kind, the only one in his league.
